What it is

The Ideal 174135 is a fan wiring harness assembly supplied by Ideal for the Mexico HE range of boilers. It is the loom that carries electrical signals and power between the boiler's control components and the fan, and may be made up of several wires bundled together or a single conductor depending on the circuit it serves.

Because the harness sits inside the appliance casing and runs close to hot components, the insulation and terminals can degrade over time, interrupting the supply to the fan.

Signs this part needs replacing

  • The fan does not run, or runs intermittently, when the boiler is called for heat
  • The boiler locks out or fails to fire despite a demand from the controls
  • Visible damage to the loom: cracked, brittle or heat-affected insulation, or exposed conductors
  • Loose, corroded or discoloured terminals at the fan plug or the harness connectors
  • Fault codes or symptoms pointing to a lost fan signal rather than a failed fan motor

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the harness suits your model
  • Confirm the existing harness part number and compare it with 174135 and the alternative number 1179857
  • Inspect the fan plug and any gaskets or seals disturbed during removal, and replace them if they are perished
